First Aid Measures

Ingestion
Mucosal if no respiratory compromise is present, dilute immediately with milk or water; no more than 8 ounces in adults and 4 ounces in children. Gastric ipecac contraindicated. Consider insertion of a small, flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions; the risk of further mucosal injury must be weighed against potential benefits.
Inhalation
Move to fresh air; call a doctor.
Skin
Wash several times with soap and water.
Eyes
Flush with water for 15 minutes, holding eyelids open; call physician.

Handling and Storage

Storage
Materials which are toxic as stored or which can decompose into toxic components.Should be stored in a cool, well ventilated place, out of the direct rays of the sun, away from areas of high fire hazard, and should be periodically inspected. Incompatible materials should be isolated.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation
Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur.
Skin
Severe skin irritation and/or burns may occur.
Eyes
Ingestion may result in burns to the lips, tongue, oral mucosa, and upper airway. Alkaline eye exposures produce distortion of cellular membranes, loss of corneal, the mucous membrane that lines the inner surface of the eyelid and the exposed surface of the eyeballl and lens epithelium and loss of endothelium of the cornea and blood vessels.
Ingestion
Burns of the esophagus and less commonly the stomach may occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns.
Hazards
Will increase the intensity of a fire. May cause fire on contact with combustibles. Containers may explode in fire. Flammable alcohol and ketone gases are formed in fire. Burns with a flare effect. Containers may explode.

Exposure Controls/Personal Protection

Personal Protection
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Exposure Effects
Abnormally low blood pressure and apnea have been reported with severe poisonings. Cerebral edema, cerebral gas embolism, cerebral infarction, and seizures have been reported following ingestion of concentrated (35%) solutions. Death has been reported as a result of embolic cerebrovascular injury.
Poison Class
2

Fire Fighting Measures

Fire Fighting
Extinguish with dry chemicals, foam or carbon dioxide. Water may be ineffective on fire. Cool exposed containers with water.
Fire Potential
This material is combustible.

Accidental Release Measures

Small spills/leaks
Stop discharge if possible. Keep people away. Avoid contact with liquid and vapor. Isolate and remove discharged material. Notify local health and pollution control agencies.

Stability and Reactivity

Incompatibilities
Aluminum, copper, brass, lead, zinc salts, mineral acids, oxidizing or reducing agents all can cause rapid decomp.
Stability
No data.
Combustion Products
Flammable alcohol and ketone gases are formed in fire.
